12Gb/s SAS RAID Controller
Mac / PC / Linux / PCIe 3.0 / SAS / s SAS / SATA
The new third generation ARC-1883 family offers advanced technology for increased performance and improved enterprise data protection. They were designed with 1.2 GHz dual core ROC processor, DDR3-1866 memory architecture and PCIe 3.0 interface for the most performance-hungry database and IT applications. The ARC-1883 family includes 8 ports low profile as well as full height 24 internal ports with additional 4 external ports with mini SAS HD connectors for 12Gb/s throughput on each port.
The 12Gb/s SAS RAID controllers raise the standard to higher performance levels with several enhancements including new high performance 1.2 GHz dual core ROC processor, a DDR3-1866 memory architecture and high performance PCIe 3.0 interface bus interconnection. The low profile controllers by default support on-board 2G of ECC DDR3-1866 SDRAM memory.
ARC-1883ix-24 RAID controllers includes one 240-pin DIMM socket with default 2GB DDR3-1866, single rank, 1Rx8, upgrade to 8GB or 8GB DDR3-1600, dual rank, 2Rx8, ECC SDRAM. The 12Gb/s SAS is designed for backward compatibility with 6Gb/s and 3Gb/s SAS and SATA hard drives. Regardless of the drive speed, 12Gb/s SAS RAID controllers will provide maximum read/write performance improvements for the most performance-hungry database and IT applications.
The ARC-1883ix includes one 12Gb/s SAS expander that incorporates the latest enhancements in SAS along with new LSI DataBolt bandwidth optimizer technology. This is designed to help facilitate the industry transition to 12Gb/s SAS-enabled systems by allowing users to take advantage of 12Gb/s speeds while utilizing existing 6Gb/s drives and backplanes. Using DataBolt, the ARC-1883ix buffers 6Gb/s data and then transfers it out to the host at 12Gb/s speeds in order to match the bandwidth between faster hosts and slower SAS or SATA devices.
The 12Gb/s SAS RAID controller support broad operating system including Windows, Linux (Open Source), FreeBSD (Open Source), Solaris (Open Source), Mac, VMware and more, along with key system monitoring features such as enclosure management (SES-2, SMP, & SGPIO) and SNMP function. Our products and technology are based on extensive testing and validation process; leverage ARC-1880/1882 series controller field-proven compatibility with operating systems, motherboards, applications and device drivers.
Designed and leveraged with Areca's existing high performance RAID solution, ARC-1883 provides superior levels performance and enterprise level data protection for the most demanding next-generation server and storage environments. It supports the hardware RAID 6 engine to allow two HDDs failures without impact the existing data and performance. It allows users to hot swap drive in the event of a drive failure with zero downtime. The optional flash-based backup module (FBM) provides power to transfer the cache data from the SDRAM memory to the NAND flash memory if it contains data not yet written to the drives when power is lost. ARC-1883 also supports traditional Lithium-ion (Li-ion) battery backup module (BBM) to protect cached data on RAID adapters.
The controllers contain an embedded McBIOS RAID manager that can access via hot key at M/B BIOS boot-up screen. This pre-boot McBIOS RAID manager can use to simplify the setup and management of RAID controller. The controller firmware also contains a browser-based McRAID storage manager which can be accessed through the Ethernet port or ArcHttp proxy server in Windows, Linux, FreeBSD and more environ- ments. The McRAID storage manager allows local and remote for all storage configuration and management needs from standard web browser. The Single Admin Portal (SAP) monitor utility can support one application to scan multiple Areca RAID units in the network.
